Answer:
x = 35°
Step-by-step explanation:
sin x = cos (90° - x)
sin 55° = cos (90° - 55°)
sin 55° = cos 35°
x = 35°
Which graph represents an exponential function?
Answer:The function that represents an exponential function is the 4th graph and it can be modeled as y = aeᵇˣ.
What are exponential functions?
The exponential functions are written in the form of y = aeᵇˣ, where the output y increases exponentially for the input x.
In order to find the graph that represents an exponential function, we will discuss each of the following graphs,
For the 1st graph, (Black),
In the first graph, the graph is of a parabola, and the function which represents this kind of graph is a quadratic equation, therefore, this graph represents a parabolic equation. It is given by the function,
y=ax²+bx+c or y=a(x-h)²+k
For the 2nd graph, (Red),
In the second graph, the graph represented is the graph of a reciprocal function, the function that can be represented by the graph,
y=a/x + b
For the 3rd graph, (Blue),
In the third graph, the graph represented is the graph of root function, it can be modeled as,
y = a+√(x+b)
For the 4th graph, (Green),
In the fourth graph, the graph represented is the graph of an exponential function, and it can be modeled as,
y = aeᵇˣ
Hence, the function that represents an exponential function is the 4th graph and it can be modeled as y = aeᵇˣ.

Answer:
1
Step-by-step explanation:
Let's say we have y=f (x)
It denotes the y value that corresponds to x.
When x=3, we can see from the graph that
The matching y value for x=3 =1
As a result, h(3)=1
The value of h(3) can be estimated from the piecewise function curve is 1. so option c is correct.
What is piecewise function?A function that is composed of several smaller functions, each with a distinct domain, is said to be piecewise. The term "piecewise" refers to the way in which these sub-functions are defined in terms of various intervals or "pieces" of the function's overall domain.
Given that,
The graph of the piecewise function
The function is divided into two piece
Interval-1 x ∈ [-4, -1)
Interval-2 x ∈ [-1, 4]
The value of the function when x is equal to 3,
In the graph it is clearly mention that for x =3
the output value of the function is 1
Hence, the output value is 1

Why would it
be better to measure the length of your classroom with
meterstick instead of a centimeter ruler?
Answer:
Meterstick
Step-by-step explanation: A standard classroom is basically just a large open room, no rooms. So it is more straight than it is curved, and if you can cover a larger area in a shorter time, it is more effecient.

11. Maria's age is 3 years more than twice George's age. Which expression represents George's age in terms of Maria's?
Answer:
C
Step-by-step explanation:
Okay, the catch of this question is that they do a very good job of explaining Maria's age in terms of George's age, but they leave George's age in terms of Maria's all up to you.
First start off by doing an expression of what they explicitly give you. Maria's age in terms of George's age.
Let's use variables g, representing George's age and m representing Maria's age
m = 2g + 3
Okay, this is all dandy and all, but they ask us for George's age in terms of Maria's, so we need to isolate for g.
subtract the 3 from both sides, like so:
m - 3 = 2g
then divide 2 from both sides: (remember we're dividing the whole thing)
(m-3)/2 = g
Now we have an expression for George's age in terms of Maria's.
g = (m-3)/2 or [tex]g = \frac{m-3}{2}[/tex]
The answer that gives us this, is C.
a thousand dollars is left in a credit union drawing 7% compounded monthly. what is the balance at the end of 10 years
Answer:
$9400
Step-by-step explanation:
You start with $1000 and get 7% more every month.
7% of 1000 is 70 so that means $70 is added to the credit union each month.
So you add $70 dollar to $1000 for every month there is which would be 12 months timers the ten years:
1000 + (70 x 12 x 10) = 9400
EXPLAIN AND SOLVE THE EQUATION
Answer:
1st answer: 61000+(X-1) x 700
2nd answer: 64500
Step-by-step explanation:
Since it says the population increases linearly, which means by the same amount, it is an arithmetic progression. So the formula to find a term in arithmetic progression is [tex]T_{n}[/tex]=a + ( n - 1 ) x d , where a is the first term, n is number of terms, and d is common difference. So now just put the values in the equation, where 61000 is a, x is n and d is 700. To find second answer put 6 in place of n as it says from 2003 to 2009 which is 6 years later.

Solve |y + 2|>6
A. {y|y<-8 or y>4}
B. {y|y<-6 or y>6}
C. {y|y<-4 or y>4}
Answer:
[tex]y < -8[/tex]
[tex]y > 4[/tex]
Step-by-step explanation:
Absolute Value Inequality entered :
|y+2|>6
Step by step solution :
Step 1: Rearrange this Absolute Value Inequality
Absolute value inequalitiy entered
|y+2| > 6
Step 2: Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |y+2|
For the Negative case we'll use -(y+2)
For the Positive case we'll use (y+2)
Step 3: Solve the Negative Case
-(y+2) > 6
Multiply
-y-2 > 6
Rearrange and Add up
-y > 8
Multiply both sides by (-1)
Remember to flip the inequality sign
y < -8
Which is the solution for the Negative Case
Step 4: Solve the Positive Case
(y+2) > 6
Rearrange and Add up
y > 4
Which is the solution for the Positive Case
Step 5:
Wrap up the solution
y < -8
y > 4

The ratio of blue jays to Robin's was 6 to 7. If there were 84 Robins, how many blue jays were there?
Answer:
72
Step-by-step explanation:
Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.
6 to 7 can also be express as 6/7
Thus, we can set up a proportion
6/7 = x/84
Now, we have to solve for x
x = 72
Hence, if there were 84 robin there would be 72 blue jays.
